Evaluating the stability of SIFT keypoints across cameras
نویسنده
چکیده
Object identification using Scale-Invariant Feature Transform (SIFT) keypoints requires stable keypoint signatures that can be reliably reproduced across variations in lighting, viewing angle, as well as camera imaging characteristics. While reproducibility has been demonstrated under various lighting and viewing angles elsewhere, this work performs an empirical evaluation of the reproducibility of SIFT keypoints and the stability of their corresponding feature signatures across a variety of camera configurations within a controlled lighting and scene arrangement.

Multiple Object Tracking Using SIFT Features and Location Matching
In recent, object recognition and tracking systems have been developed that use local invariant features from Shift Invariant Feature Transform algorithm. Most of them are implemented by distance matching of descriptor features between the reference and the next consecutive frame image. Among the matched keypoints generated from SIFT descriptor matching, there are some mismatched keypoints when...
متن کاملRemoval and injection of keypoints for SIFT-based copy-move counter-forensics
Recent studies exposed the weaknesses of scale-invariant feature transform (SIFT)-based analysis by removing keypoints without significantly deteriorating the visual quality of the counterfeited image. As a consequence, an attacker can leverage on such weaknesses to impair or directly bypass with alarming efficacy some applications that rely on SIFT. In this paper, we further investigate this t...

Targets and objects registration and tracking in a sequence of images play an important role in various areas. One of the methods in image registration is feature-based algorithm which is accomplished in two steps. The first step includes finding features of sensed and reference images. In this step, a scale space is used to reduce the sensitivity of detected features to the scale changes. Afterw...
متن کاملImage Background Matching for Identifying Suspects
Thousands of digital images may exist of a given location, some of which may show a crime in progress. One technique for identifying suspects and witnesses is to collect images of specific crime scenes from computers, cell phones, cameras and other electronic devices, and perform image matching based on image backgrounds. This paper describes an image matching technique that is used in conjunct...
متن کاملSIFT Descriptor for Binary Shape Discrimination, Classification and Matching
In this work, we study efficiency of SIFT descriptor in discrimination of binary shapes. We also analyze how the use of 2 − tuples of SIFT keypoints can affect discrimination of shapes. The study is divided into two parts, the first part serves as a primary analysis where we propose to compute overlap of classes using SIFT and a majority vote of keypoints. In the second part, we analyze both cl...
